There’s growing global alarm over Omicron – the new coronavirus variant that first emerged in South Africa. Researchers say it could be the most infectious form of the virus so far, and it might even beat current vaccines. The international response has been swift. Many countries have shut down air travel from southern Africa. The South African government says the bans are an overreaction.
Omicron has moved quickly. Now countries around the world are racing to get ahead, banning flights from the region where the variant was first discovered. South Africans suddenly find themselves cut off from the world.
